"According to the CONTEXT data, Android tablets now account for 61.2 percent of the Western European tablet market, more than double the 25.1 percent recorded the same time last year. Apple iOS devices, meanwhile, fell to 37.2 percent of Western European tablet market sales by distribution, from 71.2 percent at the same time last year." This is nothing short of a catastrophic collapse of iPad market share in Europe. Furthermore, "This analysis also screens out the effect of Windows 8, credited in some quarters with helping to drive increased tablet market share and cut into Apple’s tablet lead, but in fact with little to no impact, according to CONTEXT."

Also cause its sales which count except your business-strategy is mainly services like Google's in which case its only relevant what THERE usage-statics are and I think Google has plenty more Android users then iOS users. If competition as results has lesser Android usage then it's there competative disadvantage problem but no no GENERIC Android-usage argument.
